In a busy Newcastle kitchen or retail space, your fridge is the heartbeat of the business. When it is humming along nicely, nobody gives it a second thought. But the moment a cool room stops cooling, or a display case starts sweating, it becomes an emergency that can cost thousands in lost stock and missed trade.
At Coles Refrigeration, we get asked all the time: How often do I need to service these things?
While every business is different, there are some standard rules of thumb that will keep your gear running efficiently and help you avoid those middle-of-the-night breakdown calls.
The General Rule: Every 3 to 6 Months
For most commercial refrigeration setups, a professional service every quarter is the sweet spot. If you run a smaller operation with less foot traffic, you might get away with every six months.
However, if your units are in a high heat environment, like right next to the ovens in a commercial kitchen, or if they are opened hundreds of times a day, sticking to a three-month schedule is much safer.

Why Quarterly Servicing Matters
It is not just about ticking a compliance box. Regular maintenance addresses the small issues before they turn into the compressor has died issues.
During a standard service, a technician looks at:
- Condenser Coils: These get caked in grease and dust. If they are dirty, the fridge has to work twice as hard to stay cool, which spikes your power bill.
- Door Seals: A tiny split in a gasket lets cold air escape all day long. We check that these are airtight.
- Drain Lines: Blocked drains lead to ice build-up and water leaks on the floor, which is a major safety hazard.
- Refrigerant Levels: We check for leaks to ensure the system is at the correct pressure.
The Hidden Cost of Skipping a Service
Many business owners try to save money by waiting until something breaks to call a mechanic. This is almost always more expensive in the long run.
A unit that has not been serviced in a year can use up to 20% more electricity because it is struggling to breathe through clogged filters. Over a few months, that extra power cost usually ends up being more than the price of the service itself. Plus, a well-maintained unit can last 15 years, while a neglected one might give up the ghost after seven.
Signs You Need an Urgent Service
If you notice any of the following, do not wait for your scheduled appointment:
- The Hum Has Changed: If the motor sounds louder than usual or is making a clicking noise, something is wrong.
- Ice Build-up: You should not see ice on the back walls or on the evaporator coils.
- Spoiling Food: If your milk is turning earlier than it should, the temp is likely fluctuating.
- Water Everywhere: Puddles inside or outside the unit are a clear sign of a blocked drain or a failing seal.
Simple Maintenance You Can Do Yourself
While you should leave the gas and electrical work to the pros, there are two things you can do to help your fridge last longer:
- Keep the area clear: Do not stack boxes right against the vents of your fridge. It needs airflow to get rid of the heat it is pulling out of the cabinet.
- Clean the seals: Wipe down the door gaskets with warm soapy water once a week. This stops sugar and grease from eating away at the rubber.
